Which of the following are required when adding a network to the OSPF routing process configuration? (Choose three.) In a lab test environment, a router has learned about network 172.16.1.0 through four different dynamic routing processes. Which route will be used to reach this network? A network administrator is analyzing routing update behavior on a network that has both EIGRP and OSPF configured on all routers. Both protocols appear in the output of show ip protocols. However, only EIGRP internal routes appear in the routing tables. Which statement correctly explains the scenario?...

Refer to the exhibit. Two-way redistribution was configured between OSPF and RIP on R2. After the redistribution, R3 does not see any external routes coming from the RIP domain. The debug ip ospf database external output reveals that no external LSAs are generated for the routes. What could the problem be? A subnets keyword is missing from the R2 configuration.

In an OSPF hub-and-spoke topology, what needs to be done to ensure that the spoke routers would never be selected as DR and BDR? Because nonbroadcast networks do not elect a DR/BDR, nothing needs to be done. All routers must be configured with an OSPF interface priority of 0 (ip ospf priority) to disable the DR/BDR election process. All spoke routers need to be configured with an OSPF interface priority of 0 (ip ospf priority) so that they will not become the DR/BDR.
